Embodiment 1
[0059] 1. Population breeding of peltrelative catfish and peltedelachus vacheronii
[0060] Select yellow catfish and yellow catfish from different sources through artificial induction and artificial insemination, and cultivate them in stages until at least 2 years old. The breeding is divided into three stages of selection. The selection rate of the first stage is 60%, and the second stage is divided into male and female selection. 50% selection rate and 40% selection rate in the third stage. The overall selectivity rate was 1.2% (see figure 1 with figure 2 ).
[0061] The yellow catfish and the yellow catfish selected for the first generation were selected again according to the above-mentioned method, so as to obtain the second-generation selected yellow catfish and the yellow catfish population.
[0062] 2. Genetic testing of peltrelative catfish and peltedelachus vacheronii
